Samuel R. Delany said this quote

You know what I do? I listen to other people, stumbling about with their half thoughts and half sentences and their clumsy feelings that they can't express, and it hurts me. So I go home and burnish it and polish it and weld it to a rhythmic frame, make the dull colors gleam, mute the garish artificiality to pastels, so it doesn't hurt any more: that's my poem. I know what they want to say, and I say it for them.

In a very real way, one writes a story to find out what happens in it. Before it is written it sits in the mind like a piece of overheard gossip or a bit of intriguing tattle. The story process is like taking up such a piece of gossip, hunting down the people actually involved, questioning them, finding out what really occurred, and visiting pertinent locations. As with gossip, you can't be too surprised if important things turn up that were left out of the first-heard version entirely; or if points initially made much of turn out to have been distorted, or simply not to have happened at all.

I don’t know whether Asimov realized he was saying this as well, but as an old historical materialist, if only as an afterthought, he must have realized that he was saying too: No one here will ever look at you, read a word you write, or consider you in any situation, no matter whether the roof is falling in or the money is pouring in, without saying to him- or herself (whether in an attempt to count it or to discount it), 'Negro...' The racial situation, permeable as it might sometimes seem (and it is, yes, highly permeable), is nevertheless your total surround. Don’t you ever forget it...! And I never have.

You meet a new person, you go with him and suddenly you get a whole new city...you go down new streets, you see houses you never saw before, pass places you didn't even know were there. Everything changes.
